I had a similar problem with a '94 explorer I had a few years ago. The problem ended up being the coil pack. Do you have a shop manual?

Bert296

No i dont have a manual

I've got the same problem- check ALL your vacuum hoses, especially the ones going from the EGR and PCV to the intake. Also clean your MAF and IAC...that helped-but didn't cure- my problems. What helped me the most-but still didn't completely cure- was changing the throttle Position Sensor.

Check your catalytic converter possibly plugged.
